FUMIGATING APPARATUS.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed June 3, 1919. Serial No. 302,821.

To all whom it may concern:

Be it known that I, FRANCISCO on AsIs DEL VALLE, a citizen of the United States, and a resident of San Juan, Porto Rico, have invented certain new and useful Improvements in Fumigating Apparatus, of which the following is a specification.

My invention is an improvement in fumigating apparatus, and has for its object to provide apparatus of the character specified, especially adapted to permit the fumigation by cyanid and other poisonous gases without danger of injury to the user, wherein containers for the elements which produce the gases are provided, one of which is connected to the other to tilt to cause the contents thereofto be emptied into the other container, and wherein means is provided capable of being controlled from a distance to release and permit the container to tilt, and other means in connection therewith for indicating when the container has tilted.

In the drawings:

Figure l is a side view of the apparatus with parts broken away,

Fig. 2 is a vertical section through the acid container,

Fig. 3 is a similar view through the solenoid,

Fig. 4 is a sectional view showing the trigger.

In the present embodiment of the invention a container 1 is provided for the cyanid, and a container 2 for the acid, and the container 2 is hinged at its lower end within the container 1 near the top thereof, as indicated at 5. Referring to Fig. 2 it will be seen that the container 2 is a closed receptacle having a spout 4 at the top for permitting the contents thereof to pour out when the container is tilted, and it also has a filling opening normally closed by a plug 5.

The container also has on its bottom and near that face remote from the hinge a bumper or buffer 6, of rubber or the like for cushioning the shock of the container when it tilts. The container. 1 has a similar buffer 7 with which the buffer 6 engages. An air vent tube 8 is provided for the container 2, the said tube extending from near the bottom of the container through the top thereof as shown, and this tube is for the purpose of permitting the passage of air during filling and emptying of the container. The container is normally held upright and restrained from tilting movement by releasable latch mechanism, which is electrically controlled to release position.

The restraining means comprises a lever 9, which is pivoted to an upstanding bracket 10 on the edge of the container 1, and this lever has a downwardly extending pin or angular portion 11 which is adapted to engage an opening in a lug 12 on the container, to holdthe container from tilting. A link 13 is connected with the opposite end of the lever, and at the lower end of the link is the core 14 of a solenoid 15.

The winding of the solenoid is supplied with current from a battery 16 or other suitable source of supply, through lead wires 17 and 18. A fuse 19 is interposed in the length of the lead wire 18, and a plunger switch 20 is interposed in the length of the lead wire 17 for closing the circuit, which is normally open.

In operation the cyanid is placed in the container 1. and the acid is placed in the container 2, the pintle of the hinge 3 being detachable to permit the sa e filling of the containers. After the containers are filled, the container 2 is arranged as shown in Fig. 1, the pin 11 of the lever 9 being inserted throu h .noopening in the lug 12. lVhen the lever is so arranged, the core 14. is partly withdrawn from the solenoid. The electrical circuit being properly arranged, it will be evident that \w.\q nre on the plunger of the switch will energize the winding of the solenoid, the core will be drawn into the solenoid coil. the trigger lever 9 will be released. and the container 2 will tilt, the contents thereof pouring out on to the cyanid in the container 1.

Referring to Fig. 3 it will be seen that the inner end of the core 14 is pointed or conical as shown at 21, and this conical point is adapted to engage contact points 22 within the hollow support 23 of the solenold coil. Whenever the core is drawn into the coil, the point 21 will short circuit the lead wires 17 and 18, and the fuse 19 will be blown out, thus indicating that the device has operated, and that the acid is flowing on to the cyanid.

WVith this arrangement, the fumigation with poisonous gases may be CEIII'IQCl out as easily and as safely as with nonpoisonous gases.

I claim:

Fumigating apparatus comprising a container for chemicals, a container for acids hinged Within the first named container at the bottom or" the acid container and near the top of the chemical container to empty itself into the first named container under certain normal conditions, said acid container having a perforated lug, a latch pivoted on the chemical container and having at one end a pin for engaging the perforation of the lug, means connected with the lever for operating the same to release the acid container, and means for controlling said releasing means from a distance.
